摘要:
针对青岛某再生水厂反渗透（RO）膜夏季污堵严重、化学清洗频繁的问题，基于拆膜检查并结合RO膜面污染物分析结果，对膜清洗方法进行改进。本文对比分析了碱洗药剂种类、碱洗pH、碱洗时长、酸洗药剂种类和清洗方式对RO膜清洗效果的影响，并以清洗后一段压差降幅、标准化膜通量、标准化脱盐率等作为清洗效果评价指标。研究表明，1.5%的三聚磷酸钠+0.05%的十二烷基苯磺酸钠+液碱（pH为12.5）碱洗10 h+1.5%的柠檬酸酸洗1 h的在线清洗方式和相同条件下的离线清洗方式相组合的清洗方案更适合工程应用。改进方案实践表明，夏季RO膜污堵严重的问题得到解决，标准化膜通量保持率达到90%，清洗药剂成本节省69.7%，高压泵平均电耗降低8%。
Abstract:
In response to the severe pollution blockage and frequent chemical cleaning of the reverse osmosis membrane encountered in a reclaimed water plant in Qingdao, the cleaning method was improved by removing the membrane and combining the results of the contaminants analyzed on the membrane surface after the reverse osmosis membrane dissection. The impact of alkaline detergent types, alkaline detergent pH value, alkaline detergent duration, pickling agent types and cleaning methods on the reverse osmosis cleaning effect was compared, and the cleaning effect evaluation index was used as the reduction in the pressure difference after cleaning, standardized film flux, standardized desalination rate, etc. The results show that the online cleaning method of 1.5% sodium tripolyphosphate + 0.05% sodium dodecylbenzenesulfonate + liquid alkali (pH is 12.5) alkali washing for 10 h + 1.5% citric acid pickling for 1 h and the offline cleaning method under the same conditions is more suitable for engineering cleaning. After the project was implemented, the standardized membrane flux retention reached 90%, the cost of cleaning agents was saved by 69.7%, and the average power consumption of high-pressure pumps was reduced by about 8%, effectively solving the problem of serious pollution in reverse osmosis membrane in summer.
